FIG. 3 illustrates video system 300 in which a VMS application may beused to view video from one or more video sources. Video system 300 isan example of video system 100 although video system 300 may have analternate configuration or operate in an alternate manner. Video system300 includes cameras 301 and 302 at site A 312 and cameras 304 and 305at site B 314. Video system 300 also includes VCS 320, computer 330,computer 340, storage system 324, and storage system 354, communicationnetwork 318, and communication network 328. Video system 300 enables auser of computer 330 or computer 340 to view the location of the camerason maps which depict the orientation and surroundings of the cameras aswell as the spatial relationships between the cameras. The user may viewinformation about or video from one or more of the cameras.

Video system 300 comprises cameras at multiple sites. Cameras 301 and302 are located at site A 312. Cameras 304 and 305 are located at site B314. Site A 312 and site B 314 may be in different countries, indifferent states, in different parts of the same city, in differentbuildings, or in different areas of the same building. Each of site A312 and site B 314 may typically include many additional cameras. In oneexample, site A 312 and site B 314 are two different retail storesoperated by the same entity and each of the cameras within each storecover different departments. A typical installation will have more thantwo cameras but only two are shown at each site in FIG. 3 for the sakeof clarity. Video system 300 may also typically include additional siteswith additional cameras.

VCS 320 is an example of VCS 120 although VCS 320 may have an alternateconfiguration or operate in an alternate manner. As illustrated, VCS 320may communicate with the cameras through direct links or through anetwork, like communication network 318. Communication network 318 maybe an Internet, intranet, dedicated network, wireless network, localarea network, or other type of network, including combinations thereof.

Storage systems 324 and 354 are used for storage of video from thecameras as well as for storage of other information. Storage systems 324and 354 comprise a communication interface and components for storinginformation or video. The storage components of storage systems 324 and354 may comprise a disk drive, optical disk, flash memory, solid statememory, tape drive, or other device for storage of digital data,including combinations thereof. Storage systems 324 and 354 may alsocomprise additional interfaces for transmitting or receiving data,software, firmware, power supply, structural support, or othercomponents. Storage systems 324 and 354 may be servers, disk arrays,databases, or other devices which provide storage of digital data. Whencomputer 330 requests video associated with a particular camera, VCS 320may provide video retrieved from storage system 324 or may provide alive video stream from the camera.

Computer 330 and computer 340 are any of a variety of computers orprocessing systems which are capable of executing software applications.Computer 330 comprises display 336 and VMS application 334. Computer 340comprises display 346 and VMS application 344. By executing the VMSapplications, computers 330 and 340 display maps and the location of thecameras on those maps. The VMS applications enable a user to select acamera and see information or video associated with the selected camera.Computers 330 and 340 may also comprise memory, other software,firmware, communication components, power supply, structural support, orother components. Computers 330 and 340 may be video processing systems,video analytics systems, servers, computing systems, applicationspecific circuitry, custom hardware, or other types of processingdevices, including combinations thereof.

As illustrated in FIG. 3, computer 340 communicates with VCS 320 over adirect link while computer 330 communicates with VCS 320 throughcommunication network 328. Communication network 328 may be an Internet,intranet, dedicated network, wireless network, local area network, orother type of network, including combinations thereof.

In one example of operation of video system 300, VMS application 344 isexecuted on computer 340 in order to assist a user in monitoringactivities in retail stores at site A 312 and site B 314. Using aninterface on computer 340, VMS application 344 communicates with VCS320. VMS application 344 requests and receives configuration datarelating to cameras 301-305. The configuration data may includeinformation about the cameras, information about the location of thecameras, and information about the sites in which those cameras areinstalled. The configuration information may be available from VCS 320,storage system 324, storage system 354, or a combination thereof.

Next, VMS application 344 generates maps based on the configurationdata. The maps include the location of the cameras, layouts of thestores, the areas or departments covered by the cameras, or combinationsthereof. Graphical symbols are used to indicate the locations of thecameras on the maps. The graphical symbols may also indicate thedirections in which each of the cameras is pointed as well as thepotential range of directions in which each camera may be pointed. VMSapplication 344 displays one or more of these maps and the associatedinformation on display 346 of computer 340.

Based on the information displayed, a user of computer 340 is able toselect one of the cameras using a graphical understanding of which storethe camera is located in, which department the camera covers, andspecifically which area of the department is covered by the camera. Inthis example, the user selects camera 304 using a user interface or someother type of input device associated with computer 340. The camera isselected by moving a cursor, pointer, or other graphical indicator overthe graphical symbol which represents the location of the camera 304.

VMS application 344 receives information about camera 304 and displaysthat information to the user. The received information may includeinformation identifying camera 304, describing the scene or departmentcovered by camera 304, a background image of the scene covered by camera304, or other information. A background image may be useful if the userwants to gain an understanding of the scene covered by the selectedcamera but does not necessarily want or need to see live video from thecamera. In this case, VMS application 344 may be able to retrieve abackground image for camera 304 from storage system 324 or storagesystem 354 without requesting video from VCS 320.

In a variation of the example above, the user may indicate a desire toview video from camera 304 based on the previously displayed informationabout the camera. In this case, VCS 320 provides video received fromcamera 304 over communication network 318 to VMS application 344. VMSapplication 344 may display the video on display 346 in full screenformat or may display the video in a thumbnail view superimposed overthe map which shows the location of the video source.

VMS application 344 may also allow the user to select a second camera,camera 305 for example, and view video from both camera 304 and camera305 on display 346 superimposed on the map. In this way, the user may beable to simultaneously view a person, object or incident from multipleangles. This configuration may also enable the user to easily track aperson or object as it moves from one scene to another. The graphicallayout of the map and the indicated locations and directions of thecameras allow a remote user to gain a better spatial understanding ofthe site and use that spatial understanding to better understand thecontext of the activities taking place in the displayed video.

One skilled in the art will appreciate that the functions associatedwith VMS applications 334 and 344 and VCS 320 may be combined into asingle device or distributed across VCS 320 and the VMS applications, orother devices, in a variety of manners.

FIG. 4 illustrates four example display views generated by VMSapplication 334 of video system 300 and displayed on display 336 ofcomputer 330. In this example, two additional sites are included, site Cand site D. Sites C and D are similar to sites A and B of FIG. 3 in thatthey include video cameras which are linked to video system 300. Thefour sites may be in different geographical regions, may be differentareas within a single building, or may be any combination of physicallocations.

In this example, view A 410 is displayed on display 336 of computer 330when VMS application 334 is executed. View A 410 provides the user agraphical and spatial representation of where the sites containingcameras are located with respect to each other. The graphical icon orsymbol on display 336 associated with each site may be accompanied byother information about the location of the site including city name,state name, address, building number, site description, or otheridentifying information. In one variation of this example, sites atwhich cameras are not currently operational, active, or otherwiseavailable may be grayed-out or otherwise visually distinguished fromthose sites which have operational cameras.

In this example, the user selects site C. VMS application 334 thengenerates and displays view B 420. The list of available sites isdisplayed at the bottom of the view along with an indication thatinformation from site C is being viewed. This allows the user to viewthe map for site C as well as easily switch to a map for another site ifdesired. Based on configuration information received for site C, a mapis generated showing the different areas and camera locations for thestore at site C. In this case, the store has three areas of coverage:area A, area B, and area C. The area names may also include descriptiveinformation such as “apparel,” “tools,” “cash registers,” or other typesof descriptive information. The map also indicates the number andapproximate location of cameras through use of graphical symbols, smallblack boxes in this case.

The user then selects one of the areas displayed in view B 420 in orderto see more detailed information about the area and video coverage ofthe area. In this example, the user selects area B and VMS applicationgenerates view C 430 which shows a more detailed map of area B ondisplay 336 of computer 330 based on the previously receivedconfiguration data. The physical location of each camera in area B isindicated on the map using a graphical symbol. The graphical symbolsinclude directional arrows which indicate the direction in which eachcamera is pointed. In the case of the camera in the upper right, an arcalso indicates the available range of positioning or range of motion ofthe camera. Buttons at the bottom of view C 430 allow the user to easilyswitch to other sites or other areas with a single selection.

The map of area B in view C 430 may also include further details aboutthe store including the location of shelves, aisles, display cases,doors, cash registers, or other items. The map may also designate thelocation of departments or categories of products within the map of areaB or any other information which aids in understanding the floorplan ofthat area of the store. The map and the additional information on themap give the user a spatial and physical understanding of the areacovered by the camera. Based on this information, the user may be ableto ascertain the types of objects or activities which may be captured bythe camera without actually having to access, request, or retrieveimages or video from the camera.

The maps in view A 410, view B 420, and view C 430 have a hierarchicalrelationship. The map in view C 430 is a more detailed view of one areaof the map in view B 420 and the map in view B 420 is a more detailedview of one area of the map in view A 410. Additional tiers and branchesof the hierarchy of maps are possible.

Within view C 430, the user may get additional information about thecameras. For example, if the user hovers a cursor over, or otherwiseselects, the graphical symbol in the lower left corner of area B in viewC 430, additional information about the associated camera is displayed.This can be accomplished through use of an extensible markup language(XML) file which relates the position of the cursor to locations on themap or through other means. This additional information may include: anidentification number of the camera, a name of the camera, a name of thedepartment covered by the camera, a description of the products coveredby the camera, a description of the area covered by the camera, or otherinformation. The user is able to view this information without actuallyhaving to access, request, or receive video from the camera. Thisinformation may be stored in and received from multiple locations withinvideo system 300.

Continuing with FIG. 4, the user may view video from a camera byselecting the camera. The request is transmitted to VCS 320. VCS 320either transmits a live video stream from the selected camera orretrieves the video associated with that camera from storage system 324.In either case, video is transmitted to VMS application 334 throughcommunication network 328. VMS application 334 displays the video asillustrated in view D 440. The video is displayed in a small window, orthumbnail, which is overlaid on the map of area B. In this way, the usercan view the video and still see the map which indicates the spatialrelationship of the video to the area. In one variation of this example,the user may expand the video to full screen mode such that the videobeing viewed occupies the entire area of display 336.

The user may also use VMS application 334 to view video from two camerassimultaneously. In this case, a small window or thumbnail associatedwith each camera is overlaid on the map of the area. In this way, theuser may view the same person or activity from multiple angles if theparticular location is covered by two or more cameras. Also, the usermay also use the two videos to more easily monitor movement of a personor an object from one area of the store to another.

In a variation of the examples discussed above, VMS application 334contains information used to determine which camera, if any, covers anylocation on the map selected by the user. When a user selects alocation, VMS application 334 determines which camera best covers thatarea and displays video from that camera. In the case where there aremultiple cameras which cover that location, VMS application 334 mayoffer the user a choice of those cameras or may display backgroundimages or video from all of the applicable cameras in a mosaic styledisplay.

In addition to the functions described above, any of the VMS or VMSapplications discussed above may perform additional video processingfunctions. The additional video processing functions may includealgorithms for video analytics, motion detection, object identification,motion analysis, compression, thinning, or other functions.

In addition to security and loss prevention uses, the systems andmethods discussed above may also be used for other purposes. The systemsand methods may be used for marketing or business purposes includinganalyzing traffic patterns, determining shopper preferences, assessingcustomer behavior, determining stocking levels, modeling buyingpatterns, or for other purposes.
